To all whom it may concern.'

Be it known that I, CARL O. Lmmnos, a citizen of the United States, and resident of the borough of Brooklyn, city of New York, county of Kings, and State of New York, have invented certain new and useful Improvements in Packing Mechanism, of which the following is a specication, taken in connection with the accompanying drawings, which form a part of the same. j

This invention relates to packing mechanism and relates especially to mechanism for folding paper, such as circulars or similar printed matter, for inserting the same in envelops and for closing the envelops by sealing or by inserting the flap into the same.

In the accompanying drawings illustrating an embodiment of'this invention and 1n which the same reference numeral refers to similar parts in the several figures, Figure 1 is a side View. Fig. 2 is a planI v 1ew partly in section. Fig. v3fis a longitudinal vertical-sectional view. Fig. 4 is a transverse section. Fig. 5 is a detail. Figs. 6, 7, 8, 9 and 10 are diagrammatic sectional views showing the operationl of themechamsm.

In the illustrated embodiment of this invention, the paper which' maybe 1n the form of a printed circular or otherwlse, is passed through the folder and may be given a longitudinal fold and a transverse fold therein and this paper may be given a second transverse fold and simultaneously inserted into an envelop by the inserter. The envelop is fed from a stack by a feeder which holds the envelop in position in 'cony nection with a gripper which may operate if desired. The gripped envelop is engaged by the oscillator and oscillated into vertical receiving position. Swinging guides -then engage it and the opener operates on the separating of the opener arms'to open the 'back of the envelop and at that time the inserter forces the paper through the guides into the -envelop. The oscillator then swings the filled envelop back, the feeder releases it and an ejector throws the filled envelop into a receiver. From the receiver the envelop passes through sealing rolls which close its previously moistened flap, or, if desired, the Hap need not be moistened and in such case the filled envelop spur gears 7 passes through a suitable closer which inserts the iap into the envelop and 'effectually closes it. j

The folder indicated in the drawings comprises the feed tapes 11 mounted on suitable wheels on the shaft 12` and coperating to bring the paper against the gage 10, this gage, as is indicated in Fig. 2, being adjustable in position and being readily fastened in any desired position by the bolts 16 which operate in suitable slots 17 in the supporting members 15. These supporting members are mounted in suitable extensions 35, 36 and 28 and secured to the table 3. The shaft 12 is indicated as driven by the' sprocket chain' 34 from the shaft 33, this shaft being driven through the spur gears 32 from the shaft 39. This shaft is rotated by the skew gears 154 and 155 from the vertical shaft 152 running in the bearings 153, see Fig. 1. The lbevel gears 149 drive this shaft from the cam shaft 124 which carries the bevel gear 122 and is mounted in suitable bearings in the frame 1. The bevel gear 121 on the drive shaft 6() coperates with the bevel gear 122 and operates these shafts in unison when the drive 'pulley 42 is engaged by a suitable belt or rotated in.

any other desired way. The paper fed by the tapes 11 against thegage 10 is engaged by the longitudinal' folding knife- 8 and forced down through the cooperating longitudinal folding rolls 4. These rolls are mounted in suitable bearings 5 and 6 secured to the folding table and carry tapes 30 which run over the rolls 37 also mounted in the table. A 'longitudinal fold is thus formed in the paper in the usual way. The I folding rolls -are geared together by the-v andare rotated by the bevel gears 13, 14 fro-m the shaft 12.4 Tho folding knife is mounted in the yoke 9 at the outer end of the lever 41 which operates in the bearings 19 securedto the table. The rod 156 pivoted to this argh 41 carries the cam follower 157 cooperating with a suit- -able cam 158 on the camshaft 124. In this way, the longitudinal folding lmife is depressed at suitable intervals forcing the paper through the folding rolls.

The tapes 30 carry the folded paper against the gage 21 secured in position by the bolts 22 operating in adjusting slots 23 in the supporting members 20 mounted on the table. After engaging the gage 21 a 'transverse folding linife 25 forces the paper between the coperating transverse folding rolls 2l, these rolls carrying the feed tapes 107 as is usual in thisart and the rolls bcing mounted in the bearings 31 and 38 and geared together by the spur gears 82. 'lhe transverse folding lltnife 25 is mounted in a yoke at the outer end of the lever 26 pivoted in bearings 29. rlhe short arm 27 of this lever is pivoted to the rod 162 and as indicated in Fig. 1 the lower end of this rod carries a suitable cam follower 161 which coperates with the cam 160 driven by the bevel gears 159 from the Cain shaft 12d. In this Way, the transverse folding knife is depressed at the proper intervals and makes a transverse fold in the paper. If desired, suitable presserrolls 106 and 10d may be employed to cooperate withl the tapes 107 and to grip to some extent the folded paper fed to the inserter.

As indicated inFig. 3, a suitable envelop boa: is formed by the vertical guiding ineinbers d8 mounted in the transverse piece 49 and the meinbers 50 mounted on the rods 51, 52 and adjustably held in position in the transverse members 58 by the screws o3, see

Fig. 2. The other guiding members 5d are mounted in suitable supports 55 secured to the transverse pieces 49 and 58 by the screws 56 which operate in suitable slots 57, thus making an adjustable envelop bon'. of skeleton construction which is securely mounted upon the frame 1. The pile of envelope 417 resting in this box with their flaps downward may be pressed down properly by a suitable weight 40 resting on top of the pile cured thereto. This lever is pivoted to the cam follower 62 which engages the feeder earn 61 on the drive shaft 60, so that at proper intervals the rotation of the drive shaft in the direction indicated in lig. 3 throws forward the feeder 65 into the dotted position indicated. This movement carries an envelop from the stack 17 into position over the holding plate 116, the envelop dap being held between the feeder blade and the spring-pressed gripper 177 pivoted to the holding plate and held upward with the proper pressure by the spring 120. ln this gripped position the envelop is between the pins 118 on the oscillator arms 119 which are mounted on the shaft 117. This shaft carries the pinion 139 as indicated in llig. 1, and the rack bar ld@ engages this pinion.

The cam follower lll-2 at the lower end of nosas-vo this nach bar engages the cani lll on the cam shaft 12d and in this way gives the oscillator a partial rotation at the proper time so as to carry the envelop 176 from the position indicated inlfig. G to the vertical receiving position indicated in lfig. 7, the oscillator 'pins 118 still loosely engaging the envelop back, as is indicated. The guides 100 which may have the form of thin plates or strips are indicated in l*1 3 as mounted .on the shaft 109. Similar guides 101 may be mounted on the shaft 108' so as to oscillatc from the position indicated in lig. 3 to the vertical position indicated in llig. 7. The shafts 108 and 109 are provided with the cranlis 137 and 1311 respectively which are spring-pressed and pivot-ed to the rods 167 and 135 operated by suitable cams 138 and 136 on the cam shaft. A suitable opener is preferably mounted on the guides and may take the forni of pivoted opener arms 102 indicated in Fig. Llas pivoted upon the guides-101. lThese arms are shown as norymally held together by a light spring 170 and as being provided with the cam faces 166 which can be engaged 'by the opener wedge dll to spread the armsinto the open position indicated in Fig. 1, although it is understood that the oponer may be operated in any desired way, preferably entering the envelop and moving into engagement with its lateral edges. 'llhe wedge 49 is pivoted about the shaft 248 in the brackets 47 and the arni 46 secured to its shaft is pivoted to the link l-. The cani follower 44 engages a suitable cam 13 on the drive shaft, as is indicated in Fig. 2, and thus spreads the opener at the proper intervals. It will thus be seen that after an envelop has been fed to the holding plate and oscillated into the vertical position indicated in liig. 7 that the guides are swung down int'o" vertical position, the opener arms being4 close together at this time and entering the opening in thebaclr of the envelop. immediately thereafter the wedge spreads these arms and the opener is extended into the position indicated in llig. d, the guides and opener thus forming a channel which positively directs the paper 175 forced downward by the inserter 76 into the envelop, this operation be ing indicated in Fig. 7. 1f desired, a movable elevator 79 may be employed which is shown as secured to the elevator plate 78 which normally forms part of the inserting 'table 2, this .elevator having the closed or hoolr form indicated in Fig. 3. rlhe short arm tl@ is secured to this elevator and is pivotcd to the linh 81. llhe bell crank 82 Vis pivoted to this link and to the rod 83 which carries the cam follower 841 cooperating with the cam 85 on Athe drive shaft 60. As indicated inllig. 1., an inserter yoke 75 is formed with the bearings 711 at either end which slide on the heavy rods 165 tied together at their upper ends by the brace 163 and rigidly supported from the frame 1. The pins 73 pivot the links 72 tothis yoke and these inks are pivotedvat their lower ends to the inserter levers 71 moving about the pins 69. The short arms 68 of these levers carry the cam followers 70 which engage suitable cams 123 on the drive shaft V60, see Figs. 3 and 4. The yoke 75 is provided with a number of holes 164 so that blades of suitable width may be readily secured thereto, thelinserter blade 76 being rigidly secured to the yoke and operated through the mechanism described to force the paper 175 through the opening 77 down through the guides and into the envelop 176, as is indicated in Fig. 7, the elevator 79 being also thrown upward as indicated in that figure on the -commencement of this downward movement so as to hold the folded end of the paper 175 against the adJacent side of the inserter 76, thus assisting in forming the second transverse fold in this paper.

When the inserter 76 has moved upward the opener is released and the guides are withdrawn into the position indicated in Figs. 3 and 8. The oscillator 119 then moves in the direction indicated by the arrow in the latter figure and carries the filled envelop back on top of the feeder 65. This feeder thereupon moves backward, the envelop flap being prevented from moving therewith by the serrated upper face of the gripper 177 and by the ejector 128 which moves forward' at this time, throwing the envelop 17 6 into the receiver 96, see Fig. 9. The ejector is indicated as comprising the arms mounted on the shaft' 127. The crank 129 is secured to this shaft asindicated in Fig. 1 and a suitable spring, as indicated, and also the rod.130 may be secured to this crank. The yoke 131 on the lower-end of -this rod, carries the cam follower 132 which coperates with the cam 133 on the cam shaft, thus giving the ejector a quick move.

nient at the proper time. As indicated in Fig. 3, the receiver or shoo-iiy 96 is mounted on the shaft 146 and may be composed of several plates spaced apart and closed at the lower end by an adjustable bottom piece 97. When this bottom piece' is in position the filled envelop 176 'thrown into the receiver is carried forward by the receiver and thrown therefrom upon the tapes 163 of the closing or flap-'inserting mechanism 164. The shaft 146 of the receiver carries the pinion 145 engaged by the rack bar 143 running in the bearing 144. The yoke 147 at the lower end .of thisl rack bar carries` a suitable cam follower which engages 'he cam 148 on the cam shaft. The illetUi/nvelop is carried by the tapes 163 int engagement with the stop pins 181. Thereafter its rear edge isr engaged by the clamp 184, the lifter `183 moves under the Hap and engages and raises the edge of the envelop back and thereafter the tucker 185 tucks the flap into the opening thus formed. The clamp is vthen released and the discharge rolls 182 come down into the position indicated, pressing the envelop against. the tapes 163 'and discharging it. These parts are operated from suitable cams on the shaft 180' which is driven by the sprocket chain 115 from the shaft and this flap-l inserting -mechanism 164 operates, as has been fully described in my copending application No. 198,890, filed March 19, 1904. e If desired, the envelops maybe sealed and for this purpose a water box 112 is mounted on the bracket 114. The box carries the roll 110 rotated in any desired manner and engaged by the scraper 111. The moistening roll 93 of rubber or similar material is mounted in the arms 92 which are rigid with the crank arm 91. The link 90 is pivoted to the crank arm and its other end is pivotedto'the lever 88 rotating about the stud 89.k The cam follower 87on this lever Vengages the cam 86 on the drive shaft 60 and thus at the proper1interval raises the moistening roll from its dotted position in contact with the water drum. In its raised position indicated in Fig. 3 in full lines, the moiste'ning roll 93 engages the moistening face 94 secured to the lower surface of the feeder 65. The forward movement of the feeder moistens this face 94 which subsequently engages the gummed flap of the envelop. After being filled, as has been described, the envelop 176 passes into the receiver 96 which in this case is open at the bot-tom, the bottom piece 97 being removed. When the receiver is raised into' the vertical position indicated in Fig. 3, the filled envelop falls downward and passes between the sealing rolls 95 which are mounted'in suitable brackets 99 and are relatively adjustable as indicated. As is seen in Fig. 1, one of these rolls carries the skew gear 151 engaging a similar gearv 150 on ashaft 152 so as to rotate these sealing rolls, the belt 98 'driving th\e tapes 163 from the shaft on which the positively driven roll is mounted.

It is,- of course, understood that those familiar with this artma'y make many changes in the number, form and proportions of parts of this mechanism, parts of the same 'may be omitted and parts may be employed in connection with other devices without departing from the spirit of this invention or losing the advantages of the same.
